Nats Stats wRC+

I keep track of wRC+ or (weighted runs created) on a week to week basis. This is a stat that measures a players offensive contribution compared to the league average. In this case Jayson Werth is 60% better than the league average and Steve Lombardozzi is 37% worse. This is different than WAR because it only measures hitting, it is not cumulative and it does not take into account player position.
